PLOW.

Specification of Letters Patent.

Patented Dec. 22, 1908.

To all whom alt may concern: 7

Be it known that we, LONNIE M. Anonnws and J ESSE D. ANDREWS, citizens of the United States, residing at Rockfish, in the that many forms of plow points may be used, but in the use of some of them it is necessary to provide different adjustments of the angle at which the points enter the ground.

It is the object of our invention, therefore, to provide means for adjusting the plow points whereby they may enter the ground at the proper angle.

A further object of the invention is the provision of means for cuttin roots in using the device for ground vbrea ers. This is an essential feature in all plows used for this purpose, and we have provided a device which works in connection with the adjustpoints.

With these and other objects in view, the

invention consists of certain novel features 'is a transverse vertical section on the line 4-4 of Fig. l, and Fig. 5 is a detail perspective view of a plow point which may be used in connection with the plow.

Referring more especially to the draw ings, 1 represents the beam, which is provided at its outer end with the usual clevis 2, to which the single or double-trees may be secured. As is usual the plow beam extends back and is curved down to form the foot 3, which in this instance has attached to it the horizontal foot pieces 4, spaced apart on either side of the foot 3, and having connected thereto the wear plate 5. The forward ends of these foot pieces'have secured to them a standard 6, which is preferably made of a single piece of metal bent to form a yoke, which straddles the bowed portion of the beam and is connected at its lower ends with the foot piece 4:. In the upper end of the standard 6 we provide a suitable pawl 7, which has its outer end slidably engaging a yoke member 8, which straddles and is secured to the standard 6 by bolts 9 and 10. The latter bolts may be used as set-screws and preferably pass entirely through the yoke member 8 and through the sides of the standard 6. Interposed between the upper portion of the standard 6 and the yoke member 8 is a spiral spring, which surrounds the pawl and engages a shoulder 12, and the outer end of the pawl is provided with a ring 13, by which it may be retracted. Pivotally secured to the beam forward of the standard 6 is a root cutter 14:, which depends from the beam to a point approximately level with the plate 5, and is sharpened upon its front edge. A suitable brace 15 connects the root cutter with the standard. As the standards are separated it will be seen that there is a passage between the two for the attaching bolts 16, which secure the harrow 17, to the standard and thereby render it vertically adjustable in the slot between the standards whenever necessary.

It will be understood that the plow point shown in Fig. 5 may be attached to the standard 6 by the bolts 16 when the harrow is not being used. Also the wings 18 are adjustably secured by a bolt 19 which passes through the slot formed between the foot pieces 4 so as to permit their adjustment toward or away from the plow points. The beam is provided with suitable notches 20 in which the pawl is adapted to engage so as to hold the standard in adjusted position. It will be seen from this that the angle at which the plow points enter the ground may be adjusted to a nicety thus determining the amount of furrow that may be made before starting, and by adjusting the wings toward the front or rear of the foot pieces, or by adjusting them to have a greater or less sweep the ground may be worked exactly as could be done with a cultivator.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood with out requiring a more extended explanation.

Various changes in the form, proportion and the minor details of constructlon may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claims.

Having thus described our invention What We claim and desire to secure by Letters Patent is 1. A plow comprising a beam, a foot piece connected thereto, a standard pivoted to the foot piece and having an adjustable connection with the beam, a root cutter pivoted to the beam, and a connection between the cutter and standard.

2. A plow comprising a beam, a foot piece connected thereto, a standard pivoted to the foot piece, means carried by the standard and co-act-ing with notches in the beam to hold the standard in adjusted position, means to secure a plow point on said standard, a root cutter pivoted to the beam, and an adjustable connection between the cutter and standard.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
